Abstract
Description
- The present disclosure relates to bone screws. More particularly, the disclosure relates to bone screws of improved manufacture, structure and aesthetics, and particularly configured for promoting bone growth to and through the screw.
- Improvement is desired in the provision of bone screws. In particular, improvement is desired for the structure and manufacture of bone screws configured for promoting bone growth to and through the screw.
- In addition, a need exists for such improved bones screws that are particularly configured for use in fixation of the sacroiliac (SI) joint. The SI joint is located in the pelvis. It links the iliac bone (pelvis) to the sacrum (lowest part of the spine above the tailbone).
- The disclosure relates to a bone screw configured for promoting bone growth to and through the screw.
- In one aspect, a screw according to the disclosure includes a screw body having a head at one end of the screw and a tip at an opposite end of the screw; head threads directly attached to the screw body and continuous around the head of the screw; tip threads directly attached to the screw body and continuous around the tip of the screw; and overhanging thread portions between the head threads and the tip threads, the overhanging thread portions being spaced apart, with unthreaded channels between the overhanging thread portions and the overhanging thread portions overhanging a portion of the unthreaded channels.
- In another aspect, the disclosure provides method of manufacturing a bone screw by 3-D printing to provide the bone screw configured to have a screw body having a head at one end of the screw and a tip at an opposite end of the screw; head threads directly attached to the screw body and continuous around the head of the screw; tip threads directly attached to the screw body and continuous around the tip of the screw; and overhanging thread portions between the head threads and the tip threads, the overhanging thread portions being spaced apart, with unthreaded channels between the overhanging thread portions and the overhanging thread portions overhanging a portion of the unthreaded channels.
- Further advantages of the disclosure are apparent by reference to the detailed description when considered in conjunction with the figures, which are not to scale so as to more clearly show the details, wherein like reference numbers indicate like elements throughout the several views, and wherein:
-
FIG. 1 is a perspective view of a bone screw according to the disclosure. -
FIG. 2 is a cross-sectional view thereof. -
FIG. 3 shows a head of the screw and a drive configured to drive the screw. -
FIG. 4 is the head end view of the bone screw. -
FIG. 5 is a closeup perspective view of a head of the bone screw. -
FIG. 6 is a cross-sectional view of the head. -
FIG. 7 is a closeup view of the side of the head. -
FIG. 8 is a tip end view of the bone screw. -
FIG. 9 is a closeup side view of the tip of the bone screw. -
FIG. 10 is a closeup perspective view of the tip of the bone screw. -
FIGS. 11-14 show window features of the bone screw. - With reference to the drawings, there is shown a
bone screw 10 of improved construction and aesthetics according to the disclosure. Thebone screw 10 is particularly configured for promoting bone growth to and through the screw. Thebone screw 10 is particularly suitable for installation at the sacroiliac joint of a patient but may be used for other sites of the body. - The
bone screw 10 is preferably manufactured by 3-D printing and is most preferably printed using 3-D printing techniques know as Direct Metal Laser Sintering (DMLS) techniques using Titanium Alloy (Ti-6A1-4V). One significant advantage of manufacture of thebone screw 10 by DMLS is that thebone screw 10 may be used in surgeries as printed and requires no post-printing machining. This enables reduced manufacturing costs and enables more consistent quality with reduced labor requirements. - Manufacture of the
bone screw 10 by DMLS techniques also advantageously enables unique structures, shapes, and other features to be provided on thebone screw 10. For example, thescrew 10 has a bone receptive rugous outer surface and has porous structures on the surface of thescrew 10 and internal features of thescrew 10 as described herein. - Manufacture of the
screw 10 by DMLS has been observed to provide thebone screw 10 with a roughened surface which is believed to be advantageous for promoting bone growth. For example, as shown inFIG. 1 , thescrew 10 as formed by DMLS has abody 10 a with an exterior roughened surface over the entirety of the screw that is configured to be more receptive to bone growth onto the surface than the surface of conventional titanium screws that have a relatively smooth surface. - The manufacturing method also facilitates formation of a
head 12 of thescrew 10 that facilitate interaction of thebone screw 10 with insertion tools. As shown, thehead 12 is configured to include insertion features such as a large internal or recessed complex geometricshaped drive 12 a, such as a T-50 drive or hexalobe-shaped drive, andinternal threads 12 b within thehead 12 and below thedrive 12 a. In this manner, a compatibly configuredscrew inserter 12 c such as shown having a T-50drive 12 cc and threadedtip 12 ccc may be utilized for more secure connection between the inserter and thebone screw 10. Thedrive 12 cc fits thedrive 12 a and the threadedtip 12 ccc threads into theinternal threads 12 b. Thebone screw 10 is also formed to include acannula 14 for receiving a guide wire if desired. - The
screw 10 has a triangular cross-section and is formed to includethreads 16 configured for screwing into a bone. An upper portion of thethreads 16 continue their runout onto thehead 12 for aiding in installation of thescrew 10, and in providing a tactile feel to the physician when seating thescrew 10. Also, thethreads 16 blunt towards thehead 12 to help prevent soft tissue damage if thehead 12 of thescrew 10 is left proud. - Another feature of the
bone screw 10 enabled by the manufacturing method is the provision of overhangingthread portions 16 a. For example, as shown, thethreads 16 are continuous around thebody 10 a at thehead 12 and atip 18. However, in between thehead 12 and thetip 18 thethreads 16 are not continuous and have exposed ends which provide the overhangingthread portions 16 a. - As seen, the overhanging
thread portions 16 a are spaced-apart, withunthreaded channels 16 b between the sets of overhangingthread portions 16 a. The overhangingthread portions 16 a as shown are provided in three radially spaced apart sets but may be in other spacings. The overhangingthread portions 16 a extend above or overhanging a portion of theunthreaded channels 16 b. The combination of the overhangingthread portions 16 a and theunthreaded channels 16 b provides three fluted channels that are configured for improvement of bone collection onto thescrew 10 during installation and subsequent growth of bone onto thescrew 10. - The
tip 18 is configured as a cutting tip withcutting flutes 18 a definingcutouts 18 b (FIG. 9 ). During installation of thescrew 10 into the bone, as bone is cut thechannels 16 b fill with cut bone, which aids in fusion of the bone to thescrew 10 as the bone heals. - Another feature of the
screw 10 is the provision of openings orwindows 20 along the length of thebone screw 10 and located in theunthreaded channels 16 b between the sets of overhangingthread portions 16 a. Thewindows 20 provide access for bone graft to feed into interior portions of thescrew 10 and provide zones of continuous porosity and permeability. Thewindows 20 are provided to facilitate the growth of bone through thescrew 10 and along the surfaces of thescrew 10. - Each of the
windows 20 of one of theunthreaded channels 16 b is preferably aligned with correspondingly locatedwindows 20 of the otherunthreaded channels 16 b. As depicted, thewindows 20 are desirably oblong in shape to provide open areas while retaining strength if thescrew 10. However, thewindows 20 may be of other shape. Thewindows 20 may be of uniform or non-uniform dimension. The dimensions of thewindows 20 desirably correspond to and change to correspond to changes in the diameter and length of thescrew 10 to preserve the structural strength of thescrew 10 while still maximizing the surface area of thewindows 20 for promoting bone growth to and through thescrew 10. - One or more of the
windows 20 may be formed to include a permeable andporous fill 22 occupying thewindow 20. Thefill 22 is formed during the printing of thescrew 10 by DMLS and is integrally formed as part of the structure of the window as it is printed as shown inFIG. 12 . As shown, thescrew 10 may be formed with all of thewindows 20 open, or a combination of some of thewindows 20 open and some having thefill 22, or even all having thefill 22. - The
bone screw 10 may be provided in various dimensions and without the windows. It will be appreciated that the rough surface of the DMLS printed screw in of itself provides a surface that is favorable to promote bone growth to the screw. However, the use of thewindows 20 as described is preferred. - The foregoing description of preferred embodiments for this disclosure has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the disclosure and its practical application, and to thereby enable one of ordinary skill in the art to utilize the disclosure in various embodiments and with various modifications as are suited to the particular use contemplated.
